What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a portable ultrasound device, used at the patient's bedside, can accurately diagnose long bone fractures in the emergency department. Adults with a suspected broken arm or leg will receive both an ultrasound and a standard X-ray. Researchers will compare the two methods to see if the ultrasound is a reliable, faster, and radiation-free alternative.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Point-of-Care Ultrasound (POCUS)
What this could lead to
If POCUS proves accurate, it could speed up fracture diagnosis, reduce radiation exposure, and ease emergency room crowding.
What could go wrong
This is an observational study, not a treatment trial. POCUS may miss some fractures compared to X-rays, and results depend on operator skill.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients (18 years of age or older) presenting to the emergency departments of two major Brazilian academic hospitals: Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP) and Hospital das Clínicas da Faculdade de Medicina de Marília (HCFAMEMA). Eligible participants are those seeking care for acute extremity trauma with clinical suspicion of a long bone fracture, characterized by signs such as localized pain, visible deformity, swelling, or functional limitation. Patients presenting with open fractures, hemodynamic instability requiring immediate resuscitation, known previous fractures in the same anatomical segment, or those requiring immediate surgical intervention are excluded from this study population.
